I was around, and geeked on audio in in early 1970's. I think you have to separate the US, European and Japanese markets as very distinct from each other at that time. In the US, there was an 'old school' consisting of Marantz tube equipment (7c preamp, 9 amp, 10b tuner), some electrostats like the KLH 9 and a few other pieces that, while 'old,' were still considered legendary in the US- by then, horn speakers had pretty much fallen out of fashion for consumer audio.
Levinson's introduction of a very expensive solid state preamp which, if memory served, had a john curl phono section, ARC's introduction of the SP-3, the entry of the Linn, starting the revival of belt drive and, a little later, the dahquist DQ10, which emulated the appearance of the Quad electostat- I remember double-Advents, a cheap speaker but used in combination with the Phase Linear 700 (there was no 'A' at that time) making waves, literally and figuratively. Maggie's came into play at around that time, too- big Typami panels- played louder than the competing electrostats.
My dream in those days was to find a Dukane Ionovac. :)Of course, I was always a little strange. Still had my Phase Linear when I bought my first set of Quads. No, not a synergistic match, but the Dyna Stereo 70 was.
